# Peak vs Quick Brain

The clearest difference is ads: Quick Brain at none against Peak's shown. Peak's advantage is update cadence (fortnightly vs every 6 weeks) and device support (4 vs 2). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Peak sells 10 in-app purchases, starting at $2.99 per month and Quick Brain sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Peak ships an update fortnightly, Quick Brain every 6 weeks. The most recent releases landed on October 3, 2026 and September 17, 2026 respectively.
